HOW TO PREPARE THE MACHINE FOR OPERATION
To prepare the machine for operation, follow this procedure:
1. Connect the vacuum hose to the hose connector
on the extractor and to the end of the vacuum tube
on the floor tool.
2. Connect the solution hose to the extractor and the
floor tool. To fasten the quick disconnect fitting,
slide the knurled collar on the female coupling away
from the opening. Push the male coupling into the
female coupling. See figure 4
WARNING: Do not use water that is hotter than
140°F (60°C).
3. Before moving the extractor onto the carpet, put
clean hot water into the solution tank.
4. Add a cleaning chemical, such as Clarkare
®
Ex-
tractor Concentrate, to the hot water. For the
correct amount, follow the directions shown on the
container.
5. If the extractor removes an excess amount of foam
from the carpet, add a de-foamer such as Clarkare
®
De-foamer Concentrate to the recovery tank. The
amount needed will vary according to the amount of
detergent already in the carpet.
CAUTION: To prevent damage, use a water-
based de-foamer rather than an oil-
based de-foamer.
CAUTION: Do not leave the extractor or other
cleaning machines or tools on the
carpet when not in use. Cleaning
solution in the machines and tools
can leak onto the carpet and cause
light spots or stains.
NOTE: To order Clarkare
®
Extractor Concentrate, order
part no. 398421. To order Clarkare
®
Defoamer,
order part no. 398420.
